In order to investigate the effects of foliar application of amino acid and calcium chelate on „Golden Delicious‟ and „Granny smith‟ apple trees, a randomized complete block design with four repetitions was conducted. Apple trees were sprayed with (0, 2, 4 mg L-1) of amino acid and (0, 2, 4 mg L-1) calcium chelate and their combination. Fruit weight, fruit firmness, total soluble solids, titretable acidity and calcium content of fruits were determined. All the applied treatments significantly increased quality and quantity traits compared to the control trees in both cultivars. The combination of amino acid and calcium chelate increased weight of both cultivars. Thus, in this study combination of amino acid and calcium chelate foliar spray treatment could be recommended from results as they significantly increased quality and quantity traits of „Golden delicious‟ and „Granny smith‟ apple trees.
